Conductivity in PEO-Based Zn(II) Polymer Electrolytes

摘要

PEO-based electrolytes consisting of Zinc halides dissolved in poly(ethyleneoxide) PEO and poly(ethylene) glycol dimethyl ether (PEGM) were prepared by solution casting. Electrolytes with only PEO as the polymer appear to be principally conductors of anions. PEGM significantly increases electrolyte conductivity, particularly at room temperature, as well as the mobility of Zn(II) species.
